i This "invention'relatesto a machine fory'use l -Thefebject ofthe present inventionv isto enable 'the' vbricks 4to be rlaid more ethciently and `v`quickly'"than atjpresent, Rand also tor eliminate 'the r'mairipilation by' hando'f the mortar or;'other'gcomposition used'.

According' hereto', the apparatus comprises: broadly a container adapted to be loaded with f 1'0` composition with which"thebricln'are-'tov be.1x laid,l and `isadapt'ed to travel: along the e YuppersurfaceI ot'the wall that being built and 'to ydeposi Vthrough 1anjoutlet'- su'tlieient r of the eom'positiontollf all the joints ofther 15. last l'zlitlcourse` oifbricks, and to laythe-'bed Y for'fthenext course. f f

Fi ure 8 is a front 'view' of the gauge, and Fi ure 9 is a plan. Y Figure 10 is a view of the scraper for the gauge, and I Figure 11 and Figure 12 are cross sections through a portionoi` the device showing a modified form of the ymethod of controlling the mouth of the machine.

Referring to the drawings, the machine consist-s of a container 1 of a width corresponding to the width of the wallto be built. The drawings show, for example, a machine for awall of two stretcher bricks in thickl j ness. The container 1 has a hopper portion 2 kThis vdoor 7,*as shown in Figures 4 and 5has Yits lowerfedge so posltloned as to leave a mouth '9 above the lower edges 10 'of the side walls 'between the brickwork and the lower edge of the door. This mouth corresponds to" the thickness of the layer of mortar required tor the bed on the upper surface of'each courset of brickwork. The door is controlled by a rody 11 wherebyV it maybe brought into the positionfshown in dotted lines in Figure 4, thereby closing theY neck 6 and held in that position by a book-12 engaging the edge 13 Voi" the wall 3.

Wheels r 10a (of which there may be lany yrequired number) yon axles 14 ina framev 15, fixed to the innerside of the walls 4 'of ythe container as shown, are adapted to run kon the upper surface of the upper course of the brickwork. "When the containeris in working position upon a wall and the door 6 opened to the position'y shown in full linesk in Figure 4, mortar will pass through the neck 6 on to the brickwork and, as the container is moved in the direction of the arrow in Figures 1 or 4, the mouth 9 beneath thelower edge of the door will .permit mortar to pass through to the thickness required, fillingv as it goes the vertical joints ,between the bricks. This movement of the containerl and the mortar passing through the'mouth will give to the mortar within the container a movement which aids the filling of the vertical joints asthe neck and mouth pass over them. WVheny Y a bed of mortar has been soplacedon lthey l ot bricksfand are supported vby'nibs 17 and by "vertical p'ces'lS fixed to the straight edges. These vertical pieces are provided with vertical vslots 19 VWhich enable the straight edges vto be'secured at the `desired height on the Wall by inserting plugs 20 through the slots 14, and into Va horizontal v joint oi' the brickWo-rk. |The inner sides of the l Y f A' screedorgauge-,23.1 (see.
